【摘要】 植物标本作为保藏植物资源和植物信息的一种基本手段,为植物资源管理和利用提供了重要的科学依据。腊叶标本是最常见的标本类型,在形态分类、资源保藏中发挥着重要作用。然而,腊叶标本在长期保存中存在原色丧失、植物器官典型特征缺损、霉变、腐败和虫蛀等问题,加之馆藏标本数据量巨大,数据管理和查询成为一个非常棘手的问题,从而造成植物标本数据利用率低,无论在科研还是在进一步的开发中都没有产生应有的作用。随着信息化技术的快速发展,植物标本数字化已成为可能,并备受各方的关注。以沈阳农业大学植物标本馆馆藏蔷薇科(Rosaceae)植物腊叶标本为研究对象,采用数字化处理技术,利用计算机及其软件为辅助工具,以活体标本颜色为对照,从植物腊叶标本原色数字化恢复技术、蔷薇科植物形态数字化分类系统的构建、蔷薇科植物形态分类数据库的设计等方面进行系统研究,为模式标本的数字化及实现互联网植物分类鉴定提供技术支持。更多还原

【Abstract】 Plant specimen,as a basic means to preserve the plant resources and plant information,provide important scientific evidence for the administration and use of plant resources and cannot be replaced by written records.Plant specimen are classified into material objects and digitized specimen according to their existence pattern and appearance.Compared with the material objects,the digitized specimen collected and processed by digital technology have more advantages,which have become a heated topic in this field.The digitized landscape plant specimen can not only provide important contents for the landscape plant teaching practice,but also important references for the landscape plant design and arrangements.Though building database is an important way to normalize the collection and administration of landscape plant speimen,the process ranging from using the tools with different parameters to sorting out a good tool to use(or a computer software) and from the collecting and classifying all kinds of information to processing and building database has to be normalized.What’s more,the scheme of collection and the way of procession have to be normalized and integrated.This research centers on the scientific study of exsiccata and immersion specimens in the Plant Specimen House of Collection in Shenyang Agricultural University.By means of the computer-assisted digital technology and means,the digitized technology of the rosaceae plants exsiccata is explored in contrast to the color of living specimens,aiming at providing technical supports for digitizing type specimens and identifying plants in a taxonomic way.This paper makes a systematical research of the digitized restoration technology of the original color of plant exsiccata,the construction of the digitized classification system of plant morphology of rosaceae plants,and the design of the plant morphological classification database of rosaceae plants.更多还原
